Abstract
This invention relates to bleaching compositions. More particularly, this invention relates to bleaching compositions that provide effective and efficient bleaching performance on textiles. Such bleaching performance is obtained over an extremely wide class of stains and wide range of temperatures of the bleaching solution of pH. The bleaching compositions within the invention contain a halogenated peroxybenzoic acid and a bleach activator that contains a carbonyl carbon atom that can potentially react with such peroxybenzoic acid to form a diacyl peroxide compound or essentially any peroxycarboxylic acid and a bleach activator that contains a carbonyl carbon atom that has an alkyl group containing from about 5 to about 17 carbon atoms and can potentially react with a peroxycarboxylic acid to form a diacyl peroxide compound. In a highly preferred embodiment the bleaching compositions within the invention are detergent compositions.
